A report claims that after the release of iOS 4, 95.59% iPhone’s are running on iOS 4 though we have also got iOS 3 and iOS 2 user in a little quantity. The iOS 4 was released for iPhone 3G, iPhone 3GS and iPhone 4, iPhone 2G was kicked out to due to high requirement of processor by iOS 4. iOS 4.2.1 was the last feed to iPhone 3G (It’s damn slow :/). So it means people holding iPhone 2G are on iOS2 or iOS 3 while iPhone 3G are on iOS 3 or on iOS 4 (Hardly).

So it means that people holding iPhone’s use

iOS 4 – 95.59%

iOS 3 – 4.22%

iOS 2 – 0.17%

Now all of the geeks should fasten there seat belts for iOS 5, coming this fall.
